Definitions
- the present invention relates to absorbent articles for pet animal and packages thereof.
- a package of absorbent articles for pet animals disclosed in Patent Literature 1 includes the absorbent articles each having an absorbent panel and fastening means serving to releasably fasten both ends of the absorbent panel to each other when the article is put on a body of pet animal and a packaging bag adapted to contain a plurality of the absorbent articles.
- the absorbent panel has a topsheet lying on the side of an interior surface, a backsheet lying on the side of an exterior surface and an absorbent body interleaved between the top- and backsheets wherein the backsheet is provided on the side of its exterior surface with a mechanical fastener as a fastening system.
- a plurality of the absorbent articles, each doubled-up with the backsheet exposed on the outer side, are contained within the bag in a stacked state.
- the fastener is arranged on the exterior surface of the absorbent panel and consequently there is no anxiety that the fastener of the absorbent article put on the body of pet animal might come in contact with the body of pet animal and create a feeling of discomfort against the body.
- the fastener is exposed on the outer side of the absorbent article when the absorbent article is doubled up may cause undesirable situations.
- dust adhering to the exposed fastener may deteriorate the fastening strength of the fastener or each pair of the adjacent doubled-up absorbent articles within the packaging bag may unintentionally stick to each other by the intermediary of the respective fasteners exposed on the outer side and make it difficult to take out the absorbent articles one by one from the packaging bag.
- an absorbent article for pet animal having a longitudinal direction and a transverse direction being orthogonal to each other and an interior surface and an exterior surface opposite to the interior surface, and including an absorbent panel provided with a liquid-permeable topsheet lying on the side of the interior surface and a liquid-impermeable backsheet lying on the side of the exterior surface, and further including a fastening system functioning to releasably fasten predetermined regions of the absorbent panel to each other.
- the first aspect of the present invention lies in that the absorbent panel has a first end edge and a second end distanced from each other in the longitudinal direction and extending in the transverse direction, a first non-absorbent region extending from the absorbent region to the first end edge and a second non-absorbent region extending from the absorbent region to the second end edge; and the fastening system includes a fastener as an constituent thereof allocated on the exterior surface in the first non-absorbent region and, in a state of the absorbent panel folded at least in a manner that the interior surface of the first non-absorbent region faces the interior surface of the second non-absorbent region, the fastener is releasably caught by the exterior surface of the absorbent panel except the first non-absorbent region to maintain the folded state.
- a second aspect of the present invention relates to a package containing a plurality of the absorbent articles for pet animal.
- the second aspect of the present invention is characterized in that the absorbent panel is folded along an imaginary first transverse fold line in the absorbent region until the first non-absorbent region and an interior surface of the second non-absorbent region come in contact with each other and, in such folded state, further folded along an imaginary second transverse fold line in a lapped-over portion in which the first non-absorbent region and the second non-absorbent region are lapped over each other; and
- the absorbent article is maintained in the state folded along the imaginary first and second transverse fold lines by the intermediary of the fastener and the fastener is not caught by the other absorbent articles within the package.
- the fastener is provided on the exterior surface in the first non-absorbent region and, in the folded state of the absorbent panel so that the interior surface of the first non-absorbent region and the interior surface of the second non-absorbent region face each other, releasably caught by the exterior surface of the absorbent panel except the first non-absorbent region and thereby maintains the diaper in folded state. In this way, the fastener is not exposed in the folded state of the diaper.
- the absorbent panel is folded along an imaginary first transverse fold line in the absorbent region until the first non-absorbent region and an interior surface of the second non-absorbent region come in contact with each other and, in such folded state, further folded along an imaginary second transverse fold line in a lapped-over portion in which the first non-absorbent region and the second non-absorbent region are lapped over each other and the absorbent article is maintained in the state folded along the imaginary first and second transverse fold lines by the intermediary of the fastener and the fastener is not caught by the other absorbent articles within the package.
- the fastener is not exposed in the folded state of the diaper and, for this reason, it is easy to take out the absorbent articles from the packaging bag one by one.

- the topsheet 31 has a rectangular shape and covers the interior surface of the absorbent body 33 approximately over the entirety thereof.
- the topsheet 31 is formed of liquid-permeable fibrous nonwoven fabrics being capable of fastening and releasing the fastener 12 of the fastening system.
- various types of fibrous nonwoven fabrics well known in the relevant technical field, for example, hydrophilized spunbond fibrous nonwoven fabrics, point-bond fibrous nonwoven fabrics or air-through nonwoven fabrics may be used.
- the mechanical fastening system is composed of the fastener 12 and a predetermined region of the topsheet 31 , i.e., the nonwoven fabric defined so as to catch the fastener 12 .
- the backsheet 32 has a rectangular shape and lies on the exterior surface of the absorbent panel 11 .
- the backsheet 32 is formed of hardly-liquid-permeable or liquid-impermeable fibrous nonwoven fabrics, moisture-permeable plastic films or laminate sheets thereof.
- fibrous nonwoven fabrics for example, spunbond/meltblown/spunbond (SMS) fibrous nonwoven fabrics or spunbond fibrous nonwoven fabrics may be used.
- SMS spunbond/meltblown/spunbond
- the top- and backsheets 31 , 32 have approximately the same dimensions in the longitudinal direction Y but a dimension in the transverse direction X of the topsheet 31 is smaller than a dimension in the transverse direction X of the backsheet 32 (i.e., a dimension W1 in the transverse direction X of the diaper 10 ).
- the absorbent body 33 is formed of absorbent core materials and liquid-diffusible wrapping sheets (not shown) such as tissue paper to wrap the core materials.
- core materials wood fluff pulp, superabsorbent polymer particles or fibers which are water-soluble and have water-absorption capacity at least 10 times as high as own mass thereof or a mixture of them, in any rate, molded in a desired shape may be used.
- the absorbent body 33 is shaped in a rectangle extending in the longitudinal direction Y so far as the present embodiment is concerned, it is possible to shape the absorbent body 33 having a dimension in the transverse direction X gradually enlarged toward the middle in the longitudinal direction Y.
- the leakage-barrier sheet 34 is interleaved between the wrapping sheet of the absorbent body 33 and the backsheet 32 so as to cover the absorbent body 33 from the exterior surface thereof.

- the first and second containment sheets 36 , 37 have proximal edge portions 51 respectively extending in the longitudinal direction Y and fixed to the both side edge portions of the absorbent panel 11 , preferably to the both side edge portions of the backsheet 32 and sleeve-like or loop-like distal edge portions 52 lying on the inside of the respective proximal edge portions 51 as viewed in the transverse direction X.
- the first containment sheet 36 additionally includes a first end portion 53 and a second end portion 54 defined by end portions of the first containment sheet 36 in the longitudinal direction Y. At the proximal edge portions 51 , the first end portion 53 and the second end portion 54 , the containment sheets 35 are bonded to the respective sheets, for example, with hot melt adhesives.
- each of the distal edge portions 52 at least one string- or strand-like containment-elastic element 55 extending in the longitudinal direction Y is contractibly secured under tension. With the article put on the body of pet animal, contraction of the containment-elastic element 55 causes the distal edge portion 52 to space away from the topsheet 31 toward the body of pet animal and to form a leakage-barrier against leakage of body exudates.
- the sectional views of FIGS. 5 and 6 illustrate the distal end portions 52 of the respective containment sheets 35 in an upstanding posture. According to the present embodiment, opposite ends in the longitudinal direction Y of the respective containment-elastic elements 55 are distanced from the first and second ends 13 , 14 .
- At least one lateral elastic element 56 formed of string- or strand-like elastic element and extending in the longitudinal direction Y is disposed between the containment sheet 35 and the backsheet 32 and contractibly secured under tension.
- the lateral elastic element 56 preferably extends from the first end edge 13 to the second end edge 14 so that the contractile force of the lateral elastic element 56 may act may perform action upon the whole area from the first end edge 13 to the second end edge 14 .
- the well known joint means, for example, hot melt adhesives may used.
- the fastener 12 is located on the exterior surface of the backsheet 32 in the first non-absorbent region 22 so as to extend in the transverse direction X across the imaginary first and second longitudinal fold lines 41 , 42 and has both end portions 12 A, 12 B located in the first and second folded lateral portions 61 , 62 and an intermediate portion 12 C located between the both end portions 12 A, 12 B.
- the fastener 12 overlaps the first and second containment sheets 36 , 37 in a planar view.
- the fastener 12 includes a base material sheet bonded to the backsheet 32 and a plurality of hook elements rising from the base material sheet. These hook elements are adapted to be grabbed by and to be released from the top- and backsheets 31 , 32 .
- fastener 12 As material for the fastener 12 , olefinic materials, for example, polyethylene, polypropylene or polyester resins may be used.
- the fastener 12 may be bonded to the backsheet 32 , well known various types of bonding means such as hot melt adhesives though not shown.
- the hook elements may be replaced by pressure-sensitive adhesives though not also shown.
- release layers are preferably located over a desired region so that the fastener may be releasably adhered.
- a dimension L2 in the longitudinal direction Y of the absorbent body 33 is preferably in a range of about 20 to about 75% of a dimension in the longitudinal direction Y of the diaper 10 (i.e., a dimension in the longitudinal direction Y of the absorbent panel 11 ) L1 and more preferably about 50% or less of the dimension L1.
- the first non-absorbent region 22 and the second non-absorbent region 23 have an approximately the same dimension in the longitudinal direction Y.
- the dimension L2 of the absorbent body 33 may be set to 50% or less of the dimension L1 of the diaper 10 to restrict a tendency that the diaper 10 might become bulky due to the absorbent body 33 , thereby doubling up the diaper 10 as compactly as possible.
- a dimension L3 in the longitudinal direction Y of the fastener 12 is preferably larger than a dimension L4 in the longitudinal direction Y of a portion extending from the first end edge 13 to the end of the fastener 12 on the side of the first end edge 13 (hereinafter designated as a non-fastening portion).
- a dimension W3 in the transverse direction X of the fastener 12 is preferably larger than the dimension W2 in the transverse direction X of the absorbent body 33 , preferably larger than a dimension W4 between the imaginary first and second longitudinal fold lines 41 , 42 in the absorbent region 21 and preferably in a range of about 50 to about 90% of the dimension W1 in the transverse direction X of the diaper 10 .
- a non-fastening region is provided between the fastener 12 and the first end edge 13 to assure that this non-fastening region may be pinched with one's fingers and the grabbing effect of the fastener may be easily released.
- the dimension L3 of the fastener 12 is set to be larger than the dimension L4 of the non-fastening region to prevent the grabbing effect of the fastener 12 from being unintentionally released due to peeling off of the non-fastening region.
- the diaper 10 is put on the body of pet animal so that the topsheet 31 faces the pet animal's body, the first containment sheet 36 lies on the head side of pet animal, the second containment sheet 37 lies on the buttock side of pet animal, the absorbent region 21 lies on the ventral side of pet animal, the first and second non-absorbent regions 22 , 23 lie on the dorsal side of pet animal and finally the fastener 12 arranged on the exterior surface of the first non-absorbent region 22 is held on the interior surface (the topsheet 31 ) of the second non-absorbent region 23 .
- the dimension W3 in the transverse direction X of the fastener 12 set to be about 50% or more of the dimension W1 in the transverse direction X of the diaper 10 assures that the diaper 10 put on the body of pet animal is prevented from being displaced even when a waist dimension of pet animal significantly changes from the head toward the buttocks and the fit is sufficiently improved to prevent body exudates from leaking out.
- the arrangement that the opposite ends in the longitudinal direction Y of the second containment sheet 37 are left free brings about an advantageous effect as follows:
- the both ends of the second containment sheet 37 which are left free facilitates it to collapse the distal edge portion 52 of the second containment sheet 37 toward the buttock side and to position the penis between the first and second containment sheets 36 , 37 .
- the arrangement that the first containment sheet 36 has its both ends fixed at the first and second end portions 53 , 54 is effective to restrict a possibility that the first containment sheet 36 might collapse toward the side of pet animal's head, thereby ensuring prevention of body exudates.

- The present invention relates to absorbent articles for pet animal and packages thereof.
- Conventionally, packages are known including a packaging bag and absorbent articles for pet animals, each folded back on itself, contained in the packaging bag. For example, a package of absorbent articles for pet animals disclosed in
Patent Literature 1 includes the absorbent articles each having an absorbent panel and fastening means serving to releasably fasten both ends of the absorbent panel to each other when the article is put on a body of pet animal and a packaging bag adapted to contain a plurality of the absorbent articles. The absorbent panel has a topsheet lying on the side of an interior surface, a backsheet lying on the side of an exterior surface and an absorbent body interleaved between the top- and backsheets wherein the backsheet is provided on the side of its exterior surface with a mechanical fastener as a fastening system.

- A second aspect of the present invention relates to a package containing a plurality of the absorbent articles for pet animal.
- The second aspect of the present invention is characterized in that the absorbent panel is folded along an imaginary first transverse fold line in the absorbent region until the first non-absorbent region and an interior surface of the second non-absorbent region come in contact with each other and, in such folded state, further folded along an imaginary second transverse fold line in a lapped-over portion in which the first non-absorbent region and the second non-absorbent region are lapped over each other; and
- the absorbent article is maintained in the state folded along the imaginary first and second transverse fold lines by the intermediary of the fastener and the fastener is not caught by the other absorbent articles within the package.
- According to one or more embodiments of the absorbent article for pet animal according to the first aspect of the present invention, the fastener is provided on the exterior surface in the first non-absorbent region and, in the folded state of the absorbent panel so that the interior surface of the first non-absorbent region and the interior surface of the second non-absorbent region face each other, releasably caught by the exterior surface of the absorbent panel except the first non-absorbent region and thereby maintains the diaper in folded state. In this way, the fastener is not exposed in the folded state of the diaper.

Thetopsheet 31 is provided on its interior surface side with a pair ofcontainment sheets 35 distanced from each other in the transverse direction X and extending in the longitudinal direction Y. Theabsorbent panel 11 further includes anabsorbent region 21 in which theabsorbent body 33 is disposed, a firstnon-absorbent region 22 extending from theabsorbent region 21 to thefirst end edge 13 and a secondnon-absorbent region 23 extending from theabsorbent region 21 to thesecond end edge 14 as viewed in the longitudinal direction Y and, in addition, has first and second folded lateral portions (a pair of the folded lateral portions) 61, 62 folded inward along first and second longitudinal fold lines and acentral portion 63 defined between the first and second foldedlateral portions transverse fold line 43 overlaps theabsorbent region 21 and an imaginary secondtransverse fold line 44 overlaps the firstnon-absorbent region 22 and/or the second non-absorbentregion 23. - The first and second folded
lateral portions lateral portion 61 lies on the side of thefirst side edge 15 and the second foldedlateral portion 62 lies on the side of thesecond side edge 16. The first foldedlateral portion 61 has afirst end portion 61A and asecond end portion 61B (opposite ends in the longitudinal direction Y) distanced from each other in the longitudinal direction Y and anintermediate portion 61C extending between the first andsecond end portions lateral portion 62 has afirst end portion 62A and asecond end portion 62B (opposite ends in the longitudinal direction Y) distanced from each other in the longitudinal direction Y and anintermediate portion 62C extending between the first andsecond end portions intermediate portions lateral portions absorbent body 33 in theabsorbent region 21. - The
topsheet 31 has a rectangular shape and covers the interior surface of theabsorbent body 33 approximately over the entirety thereof. Thetopsheet 31 is formed of liquid-permeable fibrous nonwoven fabrics being capable of fastening and releasing thefastener 12 of the fastening system. As material for thetopsheet 31, various types of fibrous nonwoven fabrics well known in the relevant technical field, for example, hydrophilized spunbond fibrous nonwoven fabrics, point-bond fibrous nonwoven fabrics or air-through nonwoven fabrics may be used. The mechanical fastening system is composed of thefastener 12 and a predetermined region of thetopsheet 31, i.e., the nonwoven fabric defined so as to catch thefastener 12. - The
backsheet 32 has a rectangular shape and lies on the exterior surface of theabsorbent panel 11. Thebacksheet 32 is formed of hardly-liquid-permeable or liquid-impermeable fibrous nonwoven fabrics, moisture-permeable plastic films or laminate sheets thereof. When it is desired to use fibrous nonwoven fabrics as material for thebacksheet 32, for example, spunbond/meltblown/spunbond (SMS) fibrous nonwoven fabrics or spunbond fibrous nonwoven fabrics may be used. The top- andbacksheets topsheet 31 is smaller than a dimension in the transverse direction X of the backsheet 32 (i.e., a dimension W1 in the transverse direction X of the diaper 10). - The
absorbent body 33 is formed of absorbent core materials and liquid-diffusible wrapping sheets (not shown) such as tissue paper to wrap the core materials. As the core materials, wood fluff pulp, superabsorbent polymer particles or fibers which are water-soluble and have water-absorption capacity at least 10 times as high as own mass thereof or a mixture of them, in any rate, molded in a desired shape may be used. While theabsorbent body 33 is shaped in a rectangle extending in the longitudinal direction Y so far as the present embodiment is concerned, it is possible to shape theabsorbent body 33 having a dimension in the transverse direction X gradually enlarged toward the middle in the longitudinal direction Y. - Referring to
FIG. 5 , the leakage-barrier sheet 34 is interleaved between the wrapping sheet of theabsorbent body 33 and thebacksheet 32 so as to cover theabsorbent body 33 from the exterior surface thereof. As material for the leakage-barrier sheet 34, hardly-liquid-permeable, preferably liquid-impermeable but breathable plastic films may be used. A dimension in the longitudinal direction Y of the leakage-barrier sheet 34 is approximately the same as that of thebacksheet 32 and a dimension in the transverse direction X of the leakage-barrier sheet 34 is larger than that of thetopsheet 31 and smaller than that of thebacksheet 32. - The
containment sheet 35 includes afirst containment sheet 36 lying on the side of thefirst side edge 15 and asecond containment sheet 37 lying on the side of thesecond side edge 16. As material for the first andsecond containment sheets second containment sheets proximal edge portions 51 respectively extending in the longitudinal direction Y and fixed to the both side edge portions of theabsorbent panel 11, preferably to the both side edge portions of thebacksheet 32 and sleeve-like or loop-likedistal edge portions 52 lying on the inside of the respectiveproximal edge portions 51 as viewed in the transverse direction X. Thefirst containment sheet 36 additionally includes afirst end portion 53 and asecond end portion 54 defined by end portions of thefirst containment sheet 36 in the longitudinal direction Y. At theproximal edge portions 51, thefirst end portion 53 and thesecond end portion 54, thecontainment sheets 35 are bonded to the respective sheets, for example, with hot melt adhesives. - Within each of the
distal edge portions 52, at least one string- or strand-like containment-elastic element 55 extending in the longitudinal direction Y is contractibly secured under tension. With the article put on the body of pet animal, contraction of the containment-elastic element 55 causes thedistal edge portion 52 to space away from thetopsheet 31 toward the body of pet animal and to form a leakage-barrier against leakage of body exudates. The sectional views ofFIGS. 5 and 6 illustrate thedistal end portions 52 of therespective containment sheets 35 in an upstanding posture. According to the present embodiment, opposite ends in the longitudinal direction Y of the respective containment-elastic elements 55 are distanced from the first and second ends 13, 14. In each of theproximal edge portions 51, at least one lateralelastic element 56 formed of string- or strand-like elastic element and extending in the longitudinal direction Y is disposed between thecontainment sheet 35 and thebacksheet 32 and contractibly secured under tension. The lateralelastic element 56 preferably extends from thefirst end edge 13 to thesecond end edge 14 so that the contractile force of the lateralelastic element 56 may act may perform action upon the whole area from thefirst end edge 13 to thesecond end edge 14. For joint of the respective sheets in theabsorbent panel 11, the well known joint means, for example, hot melt adhesives may used. - Referring to
FIG. 6 , thefastener 12 is located on the exterior surface of thebacksheet 32 in the firstnon-absorbent region 22 so as to extend in the transverse direction X across the imaginary first and secondlongitudinal fold lines end portions lateral portions intermediate portion 12C located between the bothend portions fastener 12 overlaps the first andsecond containment sheets fastener 12 includes a base material sheet bonded to thebacksheet 32 and a plurality of hook elements rising from the base material sheet. These hook elements are adapted to be grabbed by and to be released from the top- andbacksheets fastener 12, olefinic materials, for example, polyethylene, polypropylene or polyester resins may be used. Thefastener 12 may be bonded to thebacksheet 32, well known various types of bonding means such as hot melt adhesives though not shown. The hook elements may be replaced by pressure-sensitive adhesives though not also shown. When the pressure-sensitive adhesives are used, release layers are preferably located over a desired region so that the fastener may be releasably adhered. - A dimension L2 in the longitudinal direction Y of the
absorbent body 33 is preferably in a range of about 20 to about 75% of a dimension in the longitudinal direction Y of the diaper 10 (i.e., a dimension in the longitudinal direction Y of the absorbent panel 11) L1 and more preferably about 50% or less of the dimension L1. The firstnon-absorbent region 22 and the secondnon-absorbent region 23 have an approximately the same dimension in the longitudinal direction Y. The dimension L2 of theabsorbent body 33 may be set to 50% or less of the dimension L1 of thediaper 10 to restrict a tendency that thediaper 10 might become bulky due to theabsorbent body 33, thereby doubling up thediaper 10 as compactly as possible. - A dimension L3 in the longitudinal direction Y of the
fastener 12 is preferably larger than a dimension L4 in the longitudinal direction Y of a portion extending from thefirst end edge 13 to the end of thefastener 12 on the side of the first end edge 13 (hereinafter designated as a non-fastening portion). A dimension W3 in the transverse direction X of thefastener 12 is preferably larger than the dimension W2 in the transverse direction X of theabsorbent body 33, preferably larger than a dimension W4 between the imaginary first and secondlongitudinal fold lines absorbent region 21 and preferably in a range of about 50 to about 90% of the dimension W1 in the transverse direction X of thediaper 10. A non-fastening region is provided between thefastener 12 and thefirst end edge 13 to assure that this non-fastening region may be pinched with one's fingers and the grabbing effect of the fastener may be easily released. Further, the dimension L3 of thefastener 12 is set to be larger than the dimension L4 of the non-fastening region to prevent the grabbing effect of thefastener 12 from being unintentionally released due to peeling off of the non-fastening region. - Referring to
FIG. 7 , thediaper 10 is put on the body of pet animal so that thetopsheet 31 faces the pet animal's body, thefirst containment sheet 36 lies on the head side of pet animal, thesecond containment sheet 37 lies on the buttock side of pet animal, theabsorbent region 21 lies on the ventral side of pet animal, the first and secondnon-absorbent regions fastener 12 arranged on the exterior surface of the firstnon-absorbent region 22 is held on the interior surface (the topsheet 31) of the secondnon-absorbent region 23. - The dimension W3 in the transverse direction X of the
fastener 12 set to be about 50% or more of the dimension W1 in the transverse direction X of thediaper 10 assures that thediaper 10 put on the body of pet animal is prevented from being displaced even when a waist dimension of pet animal significantly changes from the head toward the buttocks and the fit is sufficiently improved to prevent body exudates from leaking out. Further, the arrangement that the opposite ends in the longitudinal direction Y of thesecond containment sheet 37 are left free, brings about an advantageous effect as follows: When thefirst containment sheet 36 is positioned on the head side and thesecond containment sheet 37 is positioned on the buttock side to use thediaper 10 for a male pet animal, the both ends of thesecond containment sheet 37 which are left free, facilitates it to collapse thedistal edge portion 52 of thesecond containment sheet 37 toward the buttock side and to position the penis between the first andsecond containment sheets first containment sheet 36 has its both ends fixed at the first andsecond end portions first containment sheet 36 might collapse toward the side of pet animal's head, thereby ensuring prevention of body exudates. - Referring to
FIG. 8 (a) throughFIG. 8 (d), a method of folding thediaper 10 is exemplarily described. First, referring toFIG. 8 (a) andFIG. 8 (b), from a flatly developed state of thediaper 10, the first and secondlateral portions longitudinal fold lines FIG. 8 (c), thediaper 10 is folded along the imaginary firsttransverse fold line 43 extending in theabsorbent region 21 so that the exterior surface of the firstnon-absorbent region 22 and the interior surface of the secondnon-absorbent region 23 may face each other. In consequence of folding in this manner, the bothend portions fastener 12 are grabbed by thebacksheet 32 at the respectivesecond end portions portions end portions fastener 12. While the imaginary firsttransverse fold line 43 overlaps the transverse axis Q so far as the present embodiment is concerned, the present invention includes another embodiment in which the imaginary firsttransverse fold line 43 lies closer to the firstnon-absorbent region 22 or closer to the secondnon-absorbent region 23 than to the transverse axis Q as long as the imaginary firsttransverse fold line 43 lies in theabsorbent region 21. The present invention includes further embodiment in which the imaginary first and secondlongitudinal fold lines non-absorbent regions - Referring now to
FIG. 8 (c) andFIG. 8 (d), a first lappedzone 81 of thediaper 10 in which the first and secondnon-absorbent regions transverse fold line 44 so that the firstnon-absorbent region 22 may lie on the interior side and the secondnon-absorbent region 23 may lie on the exterior side and the first lappedzone 81 is lapped over a second lappedzone 82 in which theabsorbent body 33 is doubled up. In consequence of folding thediaper 10 in this manner, the first and secondnon-absorbent regions absorbent region 21 doubled up along the imaginary firsttransverse fold line 43 and theintermediate portion 12C of thefastener 12 is grabbed by thebacksheet 32 of theabsorbent region 21 facing theintermediate portion 12C. According to suchsecond end edge 14 of folding, According to such method of folding, the first and secondnon-absorbent regions fastener 12 at the bothend portions transverse fold line 44 is prevented. While it is essential that the imaginary secondtransverse fold line 44 overlaps at least any one of the firstnon-absorbent region 22 and the secondnon-absorbent region 23 in a planar view, the imaginary secondtransverse fold line 44 is preferably formed in the vicinity of theabsorbent body 33 in the first lappedzone 81 in which the firstnon-absorbent region 22 and the secondnon-absorbent region 23 overlap each other. - Referring to
FIG. 4 , according to the present embodiment, respective width dimensions (dimensions in the transverse direction X) d1, d2 of the first andsecond end portions lateral portion 61 are larger than a width dimension d3 of theintermediate portion 61C and width dimensions d4, d5 of the first andsecond end portions lateral portion 62 are larger than a width dimension d6 of theintermediate portion 62C. The term “width dimension” used herein means the maximum dimension in the transverse direction X in a planar view for thediaper 10 in a flatly developed state as illustrated inFIGS. 3 and 4 . Specifically, the imaginary first and secondlongitudinal fold lines absorbent body 33 and, in the first and secondnon-absorbent regions second end portions lateral portion 61 are approximately the same and the width dimensions d4, d5 of the first andsecond end portions non-absorbent regions longitudinal fold lines longitudinal fold lines longitudinal fold lines non-absorbent regions longitudinal fold lines diaper 10 is put on the body of pet animal and facilitate the bothend portions fastener 12 to be grabbed by the surface of the secondnon-absorbent region 23. -
FIG. 9 is a scale-enlarged diagram of a region IX inFIG. 8 . Thefastener 12 extends in the transverse direction X beyond the imaginary first and secondlongitudinal fold lines end portions fastener 12 may be folded back onto theintermediate portion 12C of thefastener 12. Dimensions t1, t2 in the longitudinal direction Y of thefastener 12 at the bothend portions fastener 12. The terms “the dimensions t1, t2” in the longitudinal direction Y of the bothend portions respective end portions elastic element 56 preferably extends to the first and second ends 13, 14 so that the first andsecond end portions elastic element 56, thereby being easily maintained in the states folded along the imaginary first and secondlongitudinal fold lines - Referring to
FIG. 1 andFIG. 10 , thediaper 10 in a folded state has a firstexterior surface 71 and a secondexterior surface 72 being opposite to the firstexterior surface 71. The firstexterior surface 71 is defined by thebacksheet 32 in the secondnon-absorbent region 23 and theabsorbent region 21 and the secondexterior surface 72 is defined by thebacksheet 32 in theabsorbent region 21. The firstnon-absorbent region 22 and the secondnon-absorbent region 23 are fastened to each other by the intermediary of the bothend portions fastener 12 and the firstnon-absorbent region 22 and theabsorbent region 21 are fastened to each other by the intermediary of theintermediate portion 12C of thefastener 12. The dimension W3 in the transverse direction X of thefastener 12 is larger than the dimension W4 between the first and second fold lines in theabsorbent region 21 and the imaginary first and secondlongitudinal fold lines non-absorbent regions non-absorbent region 22 and the secondnon-absorbent region 23 are engaged with each other by the intermediary of the bothend portions fastener 12 is relatively large. In consequence, it is possible to fasten the first and second non-absorbent regions at a correspondingly high fastening strength. Insuch diaper 10, thefastener 12 is grabbed by thebacksheet 32 except the firstnon-absorbent region 22 and kept in a folded state and thefastener 12 is not exposed. For this reason, it is possible to avoid the anxiety that dust might adhere to thefastener 12 and deteriorate the fastening strength thereof. -
FIG. 11 is a perspective view illustrating apackage 18 containing a plurality of thediapers 10 each in a folded state. Thepackage 18 includes a plurality of thediapers 10 and apackaging bag 19 to contain thesediapers 10 therein. Thepackaging bag 19 has anopenable portion 76 defined by perforations. A plurality of thediapers 10 are stacked in a manner that, in a pair of theadjacent diapers 10, the firstexterior surface 71 of the onediaper 10 faces the secondexterior surface 72 of theother diaper 10 and the first end edges 13 of therespective diapers 10 point to one and the same direction. In this regard, the state in which a plurality of thediapers 10 are stacked is not limited to the state as described above but it is also possible, for example, to stack thediapers 10 in a manner that, in a pair of theadjacent diapers 10, the first exterior surfaces 71 or the second exterior surfaces 72 thereof may face each other or in a manner that the respective first end edges 13 point to different directions. - If a plurality of the diapers are stacked with the respective fasteners exposed on the first or second exterior surfaces of the respective diapers as in the conventional package, already in a process of aligning the diapers, a handling person will face a bothersome problem such that the fastener of one diaper might be grabbed by the backsheet of the other diaper to interrupt an operation of aligning a plurality of the diapers and/or cause the articles to be wrinkled or torn. When it is desired to take out the diaper from the packaging bag one by one, the fastener on one diaper might be grabbed by the backsheet of the adjacent diaper and make it difficult to take out the diaper one by one. Even after the diaper has been taken out from the packaging bag, the fastener of this diaper might also grabbed by the other fibrous product. In contrast, in the
diaper 10 and thepackage 18 thereof according to the present invention, thefastener 12 is not exposed and theindividual diapers 10 are maintained in a folded state under the function of thefastener 12 so that thediapers 10 may be easily aligned and protected against being wrinkled and torn. Further, each pair of theadjacent diapers 10 is not engaged with each other by the intermediate of thefastener 12 and consequently it is easy to take out thediaper 10 from thepackaging bag 19 one by one. In addition, it is possible to take out thediaper 10 maintained in a folded state from thepackaging bag 19 one by one and, in consequence, the package according to the present invention has a high portability. Theunexposed fastener 12 does not create a feeling of discomfort against the user when his or her fingers come in contact with the fastener during taking out thediaper 10 from thepackaging bag 19 and that, after thediaper 10 has been taken out from thepackaging bag 19, thefastener 12 might be grabbed by other fibrous products. Furthermore, the imaginary secondtransverse fold line 43 is allocated in the first lapped-overportion 81 in which the first and secondnon-absorbent region portion 81 in which theabsorbent body 33 is not disposed is lapped over the second lapped-overportion 82. In this way, theabsorbent body 33 is not lapped in three or more layers and thus it is possible to keep a thickness of thediaper 10 in its folded state relatively thin, thereby increasing the number of thediapers 10 contained in thepackaging bag 19. -
FIG. 12 is a diagram exemplarily illustrating another method of folding thediaper 10 whereinFIGS. 12 (a), (b) and (d) are plan views of thediaper 10 andFIG. 12 (c) is a schematic sectional view of thediaper 10. Referring toFIGS. 12 (a) and (b), thediaper 10 is folded along the imaginary first and secondlongitudinal fold lines transverse fold line 43 allocated in theabsorbent region 21. Referring now toFIGS. 12 (c) and (d), the secondnon-absorbent portion 82 over which theabsorbent body 33 is lapped is folded as if rolled up toward the side of the first lapped-overportion 81 in which thefastener 12 is present (i.e., from the side of the imaginary firsttransverse fold line 43 to the side of the first and second end edges 13, 14). According to such method of folding, in the folded state, the bothend portions fastener 12 are respectively grabbed by thesecond end portions lateral portions intermediate portion 12C of thefastener 12 is grabbed by thebacksheet 32 in theabsorbent region 21 or the secondnon-absorbent region 23. According also to such method of folding, thefastener 12 is not exposed in the folded state of thediaper 10 to assure the effect as described above and, in addition thereto, it is possible to fold thediaper 10 more compactly. Furthermore, thediaper 10 is folded as if rolled up, and thus it is possible to restrict a possibility that folding propensities might be contracted. -
FIG. 13 is a diagram exemplarily illustrating still another method of folding thediaper 10. Referring toFIGS. 13 (a) and (b), thediaper 10 is folded along the imaginary first and secondlongitudinal fold lines transverse fold line 43 allocated in theabsorbent region 21. Referring now toFIG. 13 (b) through (d), the first and secondnon-absorbent regions transverse fold lines 44 include afirst line 45 and asecond line 46 wherein, preferably, thefirst line 45 is arranged to be close to thefastener 12 but closer to the second lapped-overportion 82 than to thefastener 12 and thesecond line 46 is allocated between thefirst line 45 and the second lapped-overportion 82 but closer to theabsorbent body 33. Thediaper 10 is folded along thefirst line 45 so that the secondnon-absorbent region 23 may lie on the inner side and the firstnon-absorbent region 22 may lie on the outer side. Then thediaper 10 is folded along thesecond line 46 so that the secondnon-absorbent region 23 and theintermediate portion 12C of thefastener 12 may lie on the inner side. In this way, theintermediate portion 12C of thefastener 12 is grabbed by thebacksheet 32 in theabsorbent region 21. - The method of folding the
diaper 10 described just above makes it possible to maintain thediaper 10 in a more firmly folded state than thediaper 10 folded according to two methods previously described. According to the methods of folding thediaper 10 as previously described, thebacksheet 32 in the secondnon-absorbent region 23 defining part of the firstexterior surface 71 is fastened by the bothend portions fastener 12 having engagement strength lower than that of theintermediate portion 12C of thefastener 12. In contrast, in thediaper 10 folded according to the present method of folding, the firstnon-absorbent region 22 defining part of the firstexterior surface 73 is grabbed by thebacksheet 32 in theabsorbent region 21 by the intermediary of theintermediate portion 12C of thefastener 12 having a relatively high fastening strength. Consequently, the fastening effect should not be easily removed and thediaper 10 is reliably maintained in the folded state. Consequentially, the first and secondnon-absorbent regions individual diaper 10, thereby assuring a high portability. - The method of folding the
diaper 10 is not limited to those exemplarily described in the present specification but, in order to ensure the advantageous inventive effects relating to the present embodiment, thefastener 12 extends in the transverse direction X beyond the imaginary first and secondlongitudinal fold lines lateral portions lateral portions longitudinal fold line 41 to extend in the longitudinal direction Y in parallel to the first foldedlateral portion 61 so that the width dimension of the first foldedlateral portion 61 may be constant and to arrange the imaginary secondlongitudinal fold line 42 extends obliquely in the first and secondnon-absorbent regions lateral portion 62 may be enlarged in the first andsecond end portions lateral portions diaper 10 according to the present invention that thefastener 12 is not exposed in the folded state of thediaper 10 and the folded state is maintained by thefastener 12. For example, it is possible to fold thediaper 10 along a plurality of fold lines extending in the transverse direction X in theabsorbent region 21. Further, it is possible to arrange thediaper 10 so that thediaper 10 is not folded along the imaginary first and secondlongitudinal fold lines diaper 10 has none of the first and second foldedlateral portions - The disclosure relating to the present invention described hereinbefore may be arranged at least as follows.
